in the usual gun, whenever the safety is in 5 the on position, itrequires an appreciable period of time to move the same to the ofi"position for firing. Under these circumstances, it is quitecommon forhunters and other persons who find it necessary to fire their gunsquickly 3 to leave the safety oil in order that the gun may be alwaysready to the. This is considered dangerous practice because the firearmmaybe accidentally discharged.

' It is the purpose of the present invention to provide a safetymechanism that is capable of being set to a plurality of safetypositions. In

other words, it is the purpose of the safety mechanism, in accordancewith the present invention, to provide a. compound safety capable, inone a position, of being quickly released so that the gun may be quicklyfired. In another position,

this safety is capable of being locked by an additional safety means.

In other words, a hunter having a gun equipped 5 with a safetymechanism, in accordance with the present invention, can keep the safetyin the quickly releasable or intermediate on position when carrying thegun under conditions where a quick shot is expected. In the eventthatthe gun was being carried over rough terrain or otherwise handled sothat a very positive safety is the primary essential, the mechanism.according to the present invention, may be set to a double locked or onposition.

One-cf the objects of the present invention,

therefore, is the provision of a'novel compound safety mechanism for agun.

Another object of the present-invention is the Q provision or" a safetymechanism having two different locking actions.

Still another object of the present invention is the provision of asafety mechanism for firearms capable of being quickly released.

5' Other objects and advantages of the invention portion of the safetymechanism in the interor counterclockwise direction, serving to keep the4 will be obvious from the detailed description which follows. ,6

Referring to the accompanying drawing:

Figure 5 is a detail, partly in section, of

mediate on position. I

Figure 6 is a perspective view of the safety pin.

Figure '7 is a perspective view of the safety lever.

Referring to Figure l of the drawing, 9 indicates a lever which isnormally spring pressed in an upward direction. As is clearlyunderstandable, this lever is merely indicative of a moving part of afirearm or striker release member. For the purposes of the presentdisclosure, it may be assumed that lever i, when moved in an upwarddirection,'releases the striker of a firearm in any suitable fashion,and when held in the position shown in Figure l prevents the firing ofthe gun.

Lever'l carries a lug 2 having a pawl engaging nose 3 which engages thehook t of the pawl 5. Pawl 5 is pivoted on a pivot 8 carried by asuitable portion of a firearm, as for example, the trigger guard 2d.Nose l carried by the pawl plunger 8 engages the pawl 5 in a notch Pawlplunger spring it, through the medium of the nose 5 and notch 9, urgesthe pawl in a backward pawl hook d in firm engagement with-the nose 3.

The depth of engagement of the pawl hook and nose is determined by theposition of the adjusting lever it, pivoted at E2, on a suitable por-'tion of the firearm. Adjusting lever it carries 'a finger it, whichbears against the pawl 5 limiting the counter-clockwise movement of thepawl and thus limiting the engagement of hook '6 and nose 3. Theposition of the adjusting lever is determined by a screw indicated atit. 1 5

Trigger 5 carried on pivot 6 has a dual engagement with the pawl 5. Thetrigger carries a plunger i6 (Figure'l) which is capable of slidingmovement in the trigger. This plunger I8 is urged into pawl engagingposition by a spring l6a. The action of this plunger positions thetrigger so that the pawl is held between the plunger I8 and finger I!carried on the trigger. Trigger spring 1|8 acting-6n plunger i9 servesto retain the trigger in its forward position.

The safety mechanism of the firearm comprises a safety lever 20 carriedon a pivot 6 having a bow 20a 0n the lower portion thereof and a cam lug2| on its upper portion. The cam lug 2| is adapted to seat in a notch 22in the lever lug 2. Slidably mounted in a hole 23 in the trigger guard24 of the firearm is a safety pin 25. The safety pin comprises a knurledhead 26 and a cut away portion indicated in general at 21. This cut-awayportion comprises a fiat upper face 28 and a cam face 29 having arelieved portion 3|i and a rise 3|.

Plunger 32 urged into a downward or safety pin engaging position byspring 23 engages the fiat face 28 and serves to retain the safety pineither in on" or off" position.

The safety pin 25 is shown in Figures 1 and 3 in the off position. Inthis position, the safety lever bow 20a, is in its extreme forwardposition, bearing against cut-out portion 30 and the cam lug 2| is inrear, disengaged position.

In this position the trigger can be operated to fire the gun. A pull onthe trigger l5 will move pawl 5 by means of plunger I6 to a forwardposition to disengage hook 4 and nose '3. In order to set the safetymechanism to on position and prevent firing of the gun, knurled head 26is pushed in, thereby sliding relieved portion 30 from the positionshown in Figure 5 to the position shown in Figure 4. Cam face 29 forcesbow 20a rearwards about its pivot B, causing the upper portion of thesafety lever carrying the cam lug 2| to move in a forward or in aclockwise direction. The cam lug 2| in moving into the forward positionshown in Figure 2, forces the lug 2 in a downward "direction and seatsin the notch 22. In this position, due to the positive engagement of thecam lug 2| and the notch 22, the gun cannot be fired since the lever Icannot move in an upward direction.

In this position, the safety is said to be on and in order to fire thegun, it is necessary not only to push the safety pin off but it is alsonecessary to move the safety lever bow 20a forward. If, however, it isdesired. to leave the safety mechanism in what is termed the"intermediate on position, as shown particularly in Figure 5, it is onlynecessary to push the safety pin to the position shown in Figure 5,without moving the safety lever.

When the safety is in this position it is capable of being quicklyreleased or moved to off. This "intermediate safe" position is,therefore, particularly adapted where a quick shot is desirable, ashereinbefore explained.

It may, therefore, be seen that the safety pin 25 functions as a primarylocking safety means capable of assuming safe and ready to firepositions, and the safety lever 20 functions as a secondary quickreleasing means. It may be further noted that the primary means orsafety pin 25 is adapted to lock the secondary means or safety lever 20against release when the safety pin is in the safe or on position. v
